Patent ES-8101843-A1 (ES)
Title: Modular, waste collecting and draining floor apparatus
IPC: A01K1/015
Filed: 1980-06-04
Abstract: An improved construction is provided for slotted, waste draining floors such as commonly employed in livestock enclosures. The apparatus employs spaced, parallel, elongate assemblies, which are preferably formed of metal extruded in generally "T" shaped cross-sectional configuration (or in generally "pi" shaped cross-sectional configuration for heavier loads) to present a slotted floor, in combination with slotted waste collection and drainage pipes, which are preferably formed by longitudinal cutting of ordinary plastic pipe, within the chambers between the assemblies. The assemblies and pipes may be made to any desired length, and the modular nature of the construction permits forming a floor of any desired width. An important advantage of the apparatus is that, since it provides for the collection and drainage of waste materials by virtue of its own simple combination of elements, it eliminates the need for an underlying waste collection pit and can be mounted either directly atop a solid sub-floor or in tiered fashion upon elevated support beams without pass through of waste materials to an underlying compartment. A particularly advantageous aspect of the improved floor construction is the manner in which the floor-presenting assemblies and the waste handling pipe or trough elements are mechanically intercoupled to enhance structural strength and stability, as well as the simple and effective way in which that is accomplished.

Title: Magneto-electric transducer for magnetic recording system and recording system comprising such a transducer.
IPC: G11B5/33
Filed: 1980-07-18
Abstract: The invention is directed to transducers for recording on (writing) and playback from (reading) a magnetizable support medium. A single transducer (head) provides both record and playback functions. Recording is carried out using a winding for inducing an external magnetic flux across a gap in the transducer and playback is carried out by sensing an internal leakage flux using a Hall effect magneto-resistive element placed outside of a gap in the head. The magneto-resistive element delivers a substantially linear electrical signal response as a function of the magnetic field applied by relative motion between the transducer gap and the support medium.
Patent ES-8205483-A1 (ES)
Title: Amplifier arrangement
IPC: H03G1/00
Filed: 1981-07-10
Abstract: An amplifier comprising at least one emitter-coupled transistor pair with a signal source connected in the emitter line. Amplifier non-linearities mainly caused by the second harmonic are compensated by supplying the base of at least one of the transistors with a compensation signal of suitable phase that is derived from either the input or the output signal of the amplifier. This results in a multiplication process which produces a second harmonic in the collector current of the two transistors which, with the correct phase of the compensation signal at the input, exactly compensates the second harmonic caused by the amplifier non-linearity. If the transistor pair is used for gain or volume control, the direct voltage between the bases of the two transistors, and the compensation signal, will both be varied.

Title: Preparation of glass container for thermoplastic closure
IPC: B29C65/00
Filed: 1982-01-18
Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described.
